Silly String Explodes Under Force From Hydraulic Press

We all love playing with silly string, and the pressurized cans of stringy foam can make quite the mess. Silly string is a synthetic based resin which contains a solvent that quickly evaporates when it comes in contact with the air. This evaporation is what allows silly string to become, well . . . string.

Invented in 1972, the creators were trying to find a product that could become an instant cast for broken bones, but ended up creating something much more fun, and maybe a little bit more useless. The inventors probably couldn't have foreseen what a wild success their product would be, and now you can see a can explode under crushing forces from a hydraulic press.
